The floating of the planets in the weightless air is due to the inner constitution of the globes, and the modernized drilling of the earth to exploit… - A. C. Bhaktivedanta Swami Prabhupada

The Kṛṣṇa consciousness movement is completely scientific... When I was registering this association in New York, some friend suggested that "Why you are giving this name 'Kṛṣṇa'? Why not put the name 'God,' 'God consciousness'?" Then "Yes, I can give the name 'God consciousness.' Then it will be confused." Because we want to preach Bhagavad-gītā as it is. That is Kṛṣṇa's speaking. And we are trying to place this Kṛṣṇa's teachings to the world. And not only that, Bhagavān, God, means Kṛṣṇa. And if I give the name of "God" instead of "Kṛṣṇa," they will bring forth so many competition of Kṛṣṇa. That is not our purpose. Kṛṣṇa means God. If God has any perfect name, that is "Kṛṣṇa." Because "Kṛṣṇa" means all-attractive. God cannot be attractive for certain person. God cannot be Christian God or a Hindu God or Muslim God. God is equally attractive for Hindu, Muslim, Christian, Buddha. That is real God. And if Hindu has manufactured some God, Christian has manufactured some God, that may be God partially, but not the Supreme God. The Supreme God is Kṛṣṇa. Īśvaraḥ paramaḥ kṛṣṇaḥ [Bs. 5.1]. Parama means supreme. God... You are also god, I am also god, and every one of us, god. Why? God means controller. So controller, every one of us is a controller to certain extent, not the complete controller. But Kṛṣṇa means the complete controller.

Although Rahu attempts to attack both the sun and the Moon, they are protected by Lord Visnu. Being very afraid of Lord Visnu’s cakra, Rahu cannot stay in front of the sun or Moon for more than a muhurta (forty-eight minutes). The phenomenon that occurs when Rahu blocks the light of the sun or Moon is called an eclipse. The attempt of the scientists of this earth to go to the Moon is as demoniac as Rahu’s attack. Of course, their attempts will be failures because no one can enter the Moon or sun so easily. Like the attack of Rahu, such attempts will certainly be failures.

Shudras does not require any training. Shudra means no training. Ordinary worker class. Otherwise other three, especially two, namely the Brahmins and Kshatriyas, they require very magnificent training.
